The JSON FormatFields implementation.
Implementations
sourceimpl JsonFields

sourcepub fn new() -> Self
pub fn new() -> Self
Returns a new JSON FormatFields implementation.

sourcefn format_fields<R: RecordFields>(
&self,
writer: &'a mut dyn Write,
fields: R
) -> Result
fn format_fields<R: RecordFields>(
&self,
writer: &'a mut dyn Write,
fields: R
) -> Result
Format the provided fields to the provided writer, returning a result.
sourcefn add_fields(&self, current: &'a mut String, fields: &Record<'_>) -> Result
fn add_fields(&self, current: &'a mut String, fields: &Record<'_>) -> Result
Record additional field(s) on an existing span.
By default, this appends a space to the current set of fields if it is
non-empty, and then calls self.format_fields. If different behavior is
required, the default implementation of this method can be overridden.
